Ikjune,
I think everyone here felt that too, waiting for update that fixes the problems & its taking forever. I too felt that too as i bought the phone when it was launch & LG promise gingerbread update soon for this phone and yes Original price was 1899
How i go around the problem so i can use this phone without throwing it out (eeer, its 1.8 k item to throw? and vent your anger.....

not a good idea so i searched for solutions around)
1. Long waiting for update...
I went around and tryout other custom roms, its nightmare at 1st, but as time goes by, alot improvement you can see & it started to look good on the phone as other users contribute solution to the phone & when you get one ROM which you like, the phone felt really good. Now the roms are more mature & stable, not as bad as the time i started. Give it a try and decide whether you want to sell off the phone after you try those roms. If you don't like it, restore your original rom & sell it off.
2. Auto reboot is so annoying...
This problem is contributed by the original charger which *somehow* overcharge the phone and screw it up, how? hmm if you read my earlier post on it, you will understand... too lengthy to start explain here again
3. I am still using the stock rom - v10e I don't know why some of the time my phone can't received sms or call.
Hehehehe its known problem as this is cause by the unstable switching between 2G & 3G network and after a while, it stop responding but it shows the phone is connected but you cant receive sms or make call. This is does not happens all the time but it happens on area where 3G is weak/overlapping of service cells. Default your phone is set to WCDMA preferred and GSM as 2nd selection.
Solution, select 'Use only 2G network' on those area, as for me, my workplace is one of the in this category, so it happens to me ALL the time until i found the solution

4. Drain battery..
Hmm, i strongly agreed

Different people have different cause, open up your phone 'Click settings ->About phone ->Battery use' and tell me what is your top 5 usage
Common causei'll list some of them down below and you decide which is your.
1. Widget/Apps - sometimes your apps have alot of sync going on and your phone cannot sleep properly and it keep draining your battery. Especially the LG's like CarHome, weather, etc or could be your installed apps that cause it. I got myself titanium to help me to backup & freeze the apps so it no longer run
2. Network switching between 3G & 2G - as i've describe above, it you turn on 'use only 2G', that problem solves 2 issues together - battery drain & phone when 'dead' until restart
3. Battery need calibrate to reset the setting - hmm too long to write, pls refer to XDA forum
Since you're on v10e, some others no longer applicable to you as it has been resolve with patches
Share with us and see if we can help each other out here until there is
PROPER solution from LG & Oh yeah, LG is in my
BOTTOM list of company in decision on any future purchase
P/S: about the network switching, for those who plan to switch over to custom rom & not on baseband 725, please follow the instruction in flashing (there will be guide and remember to flash the 4 files starting for biggest size to smallers as the biggest one is basic and the smaller ones are the *update* that fixes the problem

)
frankly, i rarely face auto reboot issue.the most is when i was on CM7..1 day kena 3 times...i tried topogigi 1.7, 1.8 and CM7..still prefer 10e better..
bro wulfredz, how to set gsm as 2nd selection?
by default, ur phone will prefer 3G over 2G...no changes needed.unless to make 2G the first selection.
